SPECIFICATTON forming part of Letters Patent No. 469,126, dated February16, 1892.

Application filed October 24, 1891. Serial No. 409,669. (No model.)

of New York, have invented a new and useful Improvement inDoor-Fasteners, of which the following is a specification.

My invention relates to an improvement in door-fasteners; and thepurpose of my invention is to provide an improved construction in adevice of this nature to contribute increased strength, coupled witheconomy in material and simplicity in use.

To the above end my invention consists in a door-fastener or door-chaincomprising flexibly-joined bars or plates firmly but flexibly secured tothe door or" jamb and a staple secured to the other part, as the j ambor door, the plates or bars being provided, respectively, with a slotand key to engage each other when the plates are brought together afterpassing through the staple.

My invention'consists, further, in the specific details of constructionand combinations of parts, all as hereinafter more fully set forth.

The drawing represents a door-fastener constructed in accordance withmyinvention and is shown in position as secured to the jamb.

A represents a plate firmly secured, as by screws or bolts, to the jamband provided with a staple t. B represents a similar plate firmlysecured to the door and having the elongated staple s. The door-chainproper comprises in its preferred form a plate 0, perforated at one end,as at r, to receive a link of a chain D, the other end of which chainpasses through the staple t on the plate A, and said bar 0 carries alsoat its upper end a turnkey E. The other part of said door chain orfastener comprises a bar F, similar to the bar 0, but preferablyshorter, and provided at its extremity with an elongated slot E of adimension in one direction to receive the key E. The bars 0 and F arejoined together by a link-hinge connection G, for which any otherflexible connection may be substituted, although it is deemed desirablethat the connection shall in any case be of metal and strong. The lengthof the chain D or of the connection G, or both, may be regulated by thedistance between the plate A and the plate B on the jamb and door,respectively.

is then turned to prevent separation of the parts. It is quite apparentthat the turn-key E may be made-self-locking or provided with means toprevent its being returned to the opening position without a speciallyconstructed key, and it is also clear that the loop afforded bythe'staple 5 may be provided in other ways, as by bending outward theplate B at its central part or securing the staple 8 directly to thedoor without the interposed plate.

I do not limit myself to the specific construction shown in the drawing,although- I prefer it for many reasons as combining simplicitylandstrength with a somewhat ornamental appearance.

The especial utility of my construction is derived from the fact that adoor-bar is provided across the door-opening to present the strongestpossible resistance to displacement,-

the strain upon the staples which secure the bar to the door beinglateral and hence in the direction of the greatest strength of thesecuring means, and the advantages of a bar and of a chain combined in asingle device.

hat I claim as new, and desire to secure by Letters Patent, is-

l.-A door-fastener comprising bars flexibly connected together atadjacent extremities and adapted to fold one upon the other, one of saidbars being flexibly connected to the door or jamb and having a lengthenabling it to extend over the door and jamb, said bars at theiropposite extremities being provided with means for retaining themtogether when folded one upon the other, and a loop or staple on thejamb or door to receive the fastener and hold the same at the flexibleconnection between the members, substantially as described.

. 2. In a door-fastener, thecombination, with a plate carrying a loop orstaple, of a plate carrying through the medium of a flexible connectiona bar 0, a bar F, a flexible hinge connection between the bars 0 and F,Whereslot E,"11inge-joint G, all connected together by after the bar Fhas been passed through as described, and plate B, carrying the staple10 the loop 01' staple it may be turned back upon 8, substantially asset forth.

' the bar 0, and a locking device comprisinga 1 key and slot on the bars0 and F, respect- GEORGINE OAMPbELL' ively, substantially as described.In presence of 3. A door-fastener comprising a plate A, WILLIAM M.SWEENY, chain t, bar 0, having key E, bar F, having HAROLD D. KEELER.
